Fungal infections of the toes and nails are commonly caused by organisms that grow in warm, moist environments. Nail fungal infections usually take longer to treat than skin infections because the medicine has to reach deep into the nail. Doctors commonly prescribe antifungal creams, powders, nail paints, or oral antifungal tablets depending on how many nails are involved and how severe the infection is. Keep your feet clean and dry, change socks regularly, avoid tight or sweaty footwear, and do not share towels, nail cutters, or shoes with others. Trim nails carefully and avoid using steroid-containing creams without medical advice because they can sometimes worsen fungal infections or hide symptoms temporarily. Please consult a dermatologist or doctor for a proper examination, as some nail conditions may appear to be fungal infections but have different causes. Seek medical care if you develop pain, swelling, pus, spreading redness, or difficulty walking due to the infected nails or toes.
